Genentech Xenon MRI Idiopathic Pulmonary Fibrosis

• Status: Recruiting
• Trial end date: 2022-03-30
• Target enrollment: 0
• Participant gender: All

Summary

The purpose of this study is being done to determine whether magnetic resonance imaging (MRI) using inhaled hyper-polarized 129 Xenon gas can help visualize impaired lung function to detect changes over time in Idiopathic Pulmonary Fibrosis (IPF) patients receiving approved IPF treatments.

Subjects will undergo an approximately hour long comprehensive MRI protocol, including administration of multiple doses of hyper-polarized 129 Xenon. The subjects will have this initial study prior to initiation of IPF therapies. Then the subjects will have repeat studies at 3, 6 and 12 months following the initiation of therapy. Additional studies including pulmonary function studies, serum for bio markers, 6 minute walk distance and a high-resolution computed tomography (HRCT) scan (only at the 6 month visit) will be performed to determine how 129 Xenon MRI performs relative to standard of care evaluations for IPF.

The MRI uses a magnet and radio waves to make diagnostic medical images of the body. There have been no ill effects reported from exposure to the magnetism or radio waves used in this test. Risks of the xenon gas are slight numbness in legs, nausea, a feeling of well-being, and mild tingling in fingertips. You will have pulmonary function testing for the study, you may experience breathlessness or dizziness during or immediately following these tests.

Criteria

Inclusion Criteria:

• Outpatients of either gender, age > 18.

• Willing and able to give informed consent and adhere to visit/protocol schedules.

(Consent must be given before any study procedures are performed)

Exclusion Criteria:

• Subject is less than 18 years old

• Subjects who have been previously on either pirfenidone or nintedanib

• MRI is contraindicated based on responses to MRI screening questionnaire

• Subject is pregnant or lactating

• Resting oxygen saturation on room air <90% on supplemental oxygen

• Respiratory illness of a bacterial or viral etiology within 30 days of MRI

• Subject with ventricular cardiac arrhythmia in the past 30 days.

• Subject has history of cardiac arrest within the last year

• Subject does not fit into 129 Xenon vest coil used for MRI

• Subject deemed unlikely to be able to comply with instructions during imaging

• Recent exacerbation (within 30 days) defined by the need for antibiotics and/or systemic steroids

• Medical or psychological conditions which, in the opinion of the investigator, might create undue risk to the subject or interfere with the subject's ability to comply with the protocol requirements
